Hi, I am probably not the bearer of good news, i have a 2007 xc90 D5.
at 45k miles the turbo blew, at 90k miles, the Turbo blew,
in august last year i noticed i had a rumble from the rear, the dealer investigated assuming it was a wheel bearing, only to find the car was only operating on front wheel drive.
The up shot of this was a new rear end, diff etc, also the front angle gears were shot, this involved detaching a spline from the gearbox, the spline had worn the gearbox badly and the gearbox had to be changed this was at about 115k miles.
the upshot of that was a bill of about £15k (sweet English pounds).
well you would have thought that would be enough trouble for one car with low mileage for a volvo, but no i have a warning light coming up on the dash telling me that Anti skid service is required, this results in the car going to 2 wheel drive, this apparently is the DEM unit that needs replacing.
My advice is do what i am going to do and bin it and get a BMW X5
Sorry it might not be what you wanted to hear but it is the truth, this is my 3rd Volvo, the other 2 were the best cars anyone would want to own but after this i cant have another
